Function Interface

06-15-2009, 06:41 AM

JASS:

scope test

//imagine this is a system ( does not complie properly .... )

function interface what takes unit target returns nothing

private function test takes nothing returns nothing
       local unit u = GetTriggerUnit()
       call what.execute(u)
       set u = null
endfunction

endscope

// And this is the external function to call the system

scope test

private function abc takes unit target returns nothing
    local what d = what.abc
    call KillUnit(target)
endfunction

endscope

Doing it right or wrong and explain to me how to make it work or how does it work. Don't link me to jasshelper because I have seen it.

what is a typename... .execute should be called on the instance, not the type itself.

private function test takes nothing returns nothing
       local unit u = GetTriggerUnit()
       local what d
       call d.execute(u) // starting the instance in the "system"
       set u = null
endfunction

endscope

// And this is the external function to call the system

scope test


private function abc takes unit target returns nothing
    local what d = what.abc // so when d.execute is called upon that instance this should fire too?
    call KillUnit(target) // killing it
endfunction

endscope

Something like this?

That will now compile, but will do nothing. You need to pass the instance from outside via parameters or globals.

Edit: Oh, I didn't notice the signature inconsistency...

JASS:

function interface MyInterface takes unit someUnit returns nothing

private function testFunction takes unit u returns nothing
       call KillUnit(u)
endfunction

// ==========

local MyInterface f = testFunction
call f.execute( any_unit_you_would_like_to_kill )
